Cycle power to the instrument after connecting the sensor or... 2.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 Section 4.0 Display and Operation 4.1 User Interface The T56 has a large display which shows two live measurement readouts in large digits and up to six additional process variables or diagnostic parameters concurrently. The display is back-lit and the format can be customized to meet user requirements. The ENTER/MENU key allows access to Calibration, Hold (of current outputs), Programming, Display, Data and HART functions.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 The ENTER/MENU key is also used to enter selections or enable programming and calibration steps. The EXIT key returns to the previous menu level. The INFO key provides detailed instructions and explanations during programming and calibrating procedures. It also provides troubleshooting tips for all faults and warnings that may occur during calibration or continuous operation in process.
Instruction Manual PN-51-T56 4.4 Clarity II T56 May 2012 Menu System The T56 menu system is similar to a computer. Pressing the ENTER/MENU key at any time opens the top-level menu including Calibration, Hold, Programming, Display, Data and HART functions. To find a menu item, use the directional Navigation keys to highlight a menu item. Press ENTER/MENU and simply direct the cursor to the desired operation and follow the screen prompts.

When entering the correct access code for All security level, the user has access to all menu functions, including Programming, Calibration, Hold and Display.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 To reset to factory defaults, reset calibration data only or reset analog outputs only, access the Reset screen by pressing ENTER/MENU from the main screen. 5.7 Programming Alarm Relays The T56 24VDC (-02 order code) and the AC switching power supply (-03 order code) provide four alarm relays for process measurement or temperature. Each alarm can be configured as a fault alarm instead of a process alarm.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 5. To enter setpoints for relays, enter the desired value for the process measurement or temperature at which to activate an alarm event and press ENTER/MENU. 6. To set deadband as a measurement value, enter the change in the process value needed after the relay deactivates to return to normal (and thereby preventing repeated alarm activation) and press ENTER/MENU. 7. To set the Normal alarm condition, select Open or Closed and press ENTER/MENU.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 Section 6.0 Programming - Turbidity 6.1 Programming Measurements – Introduction The T56 automatically recognizes each installed measurement board upon first power-up and each time the analyzer is powered. Completion of Quick Start screens upon first power up enable measurements, but additional steps may be required to program the analyzer for the desired measurement application. 6.

Instruction Manual PN-51-T56 Clarity II T56 May 2012 Section 7.0 Calibration 7.1 Calibration – Introduction Calibration is the process of adjusting or standardizing the analyzer to a lab test or a calibrated laboratory instrument, or standardizing to some known reference. Completion of Quick Start upon first power up enables live measurements but does not ensure accurate readings in the lab or in process. Calibration should be performed with each attached sensor to ensure accurate, repeatable readings.
Instruction Manual PN-51-T56 7.2.1 Clarity II T56 May 2012 Slope Calibration – Turbidity This section describes how to conduct a 2-point calibration of the turbidity sensor against a user-prepared 20NTU standard. The calibration requires two steps. First, immerse the sensor in filtered water having very low turbidity and measure the sensor output. Next, increase the turbidity of the filtered water by a known amount, typically 20 NTU, and measure the sensor output again.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 Section 8.0 Maintenance 8.1 Overview The 56 Analyzer used in the Clarity II turbidimeter needs little routine maintenance. Clean the analyzer case and front panel by wiping it with a clean soft cloth dampened with water ONLY. Do not use solvents, like alcohol, that might cause a buildup of static charge. A few of the components of the analyzer are replaceable. See Tables 8-1 and 8-2. WARNING Explosion Hazard.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 NOTE: If you have a dual input analyzer, you can reapply power at this point. The initial reading from the other sensor will be momentarily zero. After about 60 seconds the reading will reach its final value. 3. Using a small Phillips screwdriver, remove the two screws holding the top flange of the sensor to the body. Fig. 8-1 Replacing the Lamp/LED Board Step 4 4.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 8.3 Debubbler and Measuring Chamber 8.3.1 Cleaning the sensor 1. Turn off the sample supply to the debubbler. WARNING BEFORE DISCONNECTING THE SAMPLE AND DRAIN LINES OR REMOVING THE SENSOR, be absolutely certain the process pressure is reduced to 0 psig and the process temperature is at a safe level. 2. Remove the sensor and put it in a safe place. The calibration cup is a good place to store the sensor. 3.

Instruction Manual Clarity II T56 PN-51-T56 May 2012 Section 9.0 Return of Material 9.1 General To expedite the repair and return of instruments, proper communication between the customer and the factory is important. Before returning a product for repair, call 1-949-7578500 for a Return Materials Authorization (RMA) number. 9.2 Warranty Repair The following is the procedure for returning instruments still under warranty: 1. Call Rosemount Analytical for authorization. 2.
Instruction Manual Clarity II T56 PN-51-T56 May 2012 Appendix This procedure describes how to verify linearity between turbidity and TSS. 1. Collect a sample of the process liquid-you may need 10 L or more if you use the Clarity II for measuring turbidity. If you use a laboratory turbidimeter, you will need less volume. The Clarity II requires about 500 mL for the measurement; laboratory turbidimeters require 50 mL or less. Verify that the turbidity of the sample is less than 200 NTU.
